Ideological Contestation on Twitter Over Diversity: Constructions of Diversity as Clashing Projects

The problematic of diversity today circulates a discourse on human differences and similarities which is also taken up by actors with controversial political agendas, notably right-wing populist and neoconservative movements. Focusing on contestation over the meaning of “diversity” by lay actors in social media, we suggest here that different constructions of diversity may be seen as clashing projects largely shaping each other through their emphasis on differences or similarities among people. In a qualitative analysis on the tweets mentioning diversity in Greek over a year, constructions of diversity were mirror images of each other across two independent ideological tensions, with distinct social stakes. Individualist constructions of diversity praising individuals' differences clashed over the legitimation of power with majoritarianist constructions emphasizing social homogeneity, and universalist constructions of diversity advocating the fundamental similarities of individuals clashed over the legitimation of social identities with particularist constructions praising cultural differences. Those constructions converse with basic social psychological models of diversity, suggesting that the emphasis on difference or similarity across people may stem from a dynamic context of political confrontation. The findings also suggest that right-wing populist representations may be channeled by the content of contestation and the positions held by the other side.     

High and Low Reading Comprehension Achievers' Strategic Behaviors and Their Relation to Performance in a Reading Comprehension Situation

This study aimed at investigating the actual strategic behaviors of high and low achievers in reading comprehension and their relation with respective performance. The participants were 45 individually examined third graders, 20 high and 25 low reading comprehension achievers. Cognitive, metacognitive, and motivational aspects of the participants' strategic behaviors during text comprehension was directly recorded by two observers by means of a structured observation form. The results revealed a relatively different profile of strategic behaviors between high and low achievers. Students' strategic behaviors during dealing with text comprehension were strongly related to respective performance for both groups.     

Essentialism in Social Representations of Citizenship: An Analysis of Greeks' and Migrants' Discourse

Following a Social Representations approach, the article examines the representations of citizenship held by both migrants and Greek citizens in Greece after the announcement of a heavily debated citizenship legislation. Essentialism, a way of representing social categories as holding an underlying essence that determines their characteristics, was used as an analytical tool to understand the inclusive or exclusive function of representations of citizenship towards migrants. Findings showed that Greeks construct representations based on ethnic, civic, and cultural ideas, while migrants construct representation of citizenship based on civic and cultural ideas. Essentialism was a way of constructing ethnic and cultural representations of citizenship and functioned in both exclusive and inclusive ways, but assimilatory terms accordingly. Civic and cultural representations of citizenship were constructed in nonessentialist ways and functioned in inclusive ways. However, from Greeks' perspective, civic inclusion was conditioned upon an often‐questioned legality of migrants and upon cultural assimilation terms. Studying both the content and the essentialist/nonessentialist formulation of representations of citizenship is an important tool in understanding the politics of inclusion and exclusion of citizens in the social arena.     

Timed picture naming in seven languages

Timed picture naming was compared in seven languages that vary along dimensions known to affect lexical access. Analyses over items focused on factors that determine cross-language universals and cross-language disparities. With regard to universals, number of alternative names had large effects on reaction time within and across languages after target-name agreement was controlled, suggesting inhibitory effects from lexical competitors. For all the languages, word frequency and goodness of depiction had large effects, but objective picture complexity did not. Effects of word structure variables (length, syllable structure, compounding, and initial frication) varied markedly over languages. Strong cross-language correlations were found in naming latencies, frequency, and length. Other-language frequency effects were observed (e.g., Chinese frequencies predicting Spanish reaction times) even after within-language effects were controlled (e.g., Spanish frequencies predicting Spanish reaction times). These surprising cross-language correlations challenge widely held assumptions about the lexical locus of length and frequency effects, suggesting instead that they may (at least in part) reflect familiarity and accessibility at a conceptual level that is shared over languages.     

Generalized latent trait models

In this paper we discuss a general model framework within which manifest variables with different distributions in the exponential family can be analyzed with a latent trait model. A unified maximum likelihood method for estimating the parameters of the generalized latent trait model will be presented. We discuss in addition the scoring of individuals on the latent dimensions. The general framework presented allows, not only the analysis of manifest variables all of one type but also the simultaneous analysis of a collection of variables with different distributions. The approach used analyzes the data as they are by making assumptions about the distribution of the manifest variables directly.     

A Composite Likelihood Inference in Latent Variable Models for Ordinal Longitudinal Responses

The paper proposes a composite likelihood estimation approach that uses bivariate instead of multivariate marginal probabilities for ordinal longitudinal responses using a latent variable model. The model considers time-dependent latent variables and item-specific random effects to be accountable for the interdependencies of the multivariate ordinal items. Time-dependent latent variables are linked with an autoregressive model. Simulation results have shown composite likelihood estimators to have a small amount of bias and mean square error and as such they are feasible alternatives to full maximum likelihood. Model selection criteria developed for composite likelihood estimation are used in the applications. Furthermore, lower-order residuals are used as measures-of-fit for the selected models.     

Generalized latent variable models with non‐linear effects

Until recently, item response models such as the factor analysis model for metric responses, the two‐parameter logistic model for binary responses and the multinomial model for nominal responses considered only the main effects of latent variables without allowing for interaction or polynomial latent variable effects. However, non‐linear relationships among the latent variables might be necessary in real applications. Methods for fitting models with non‐linear latent terms have been developed mainly under the structural equation modelling approach. In this paper, we consider a latent variable model framework for mixed responses (metric and categorical) that allows inclusion of both non‐linear latent and covariate effects. The model parameters are estimated using full maximum likelihood based on a hybrid integration–maximization algorithm. Finally, a method for obtaining factor scores based on multiple imputation is proposed here for the non‐linear model.     

Children and adolescents with idiopathic scoliosis: emotional reactions, coping mechanisms, and self-esteem

The main aim of the present study was to investigate the relationship among emotional responses of children and adolescents with idiopathic scoliosis towards their physical state, the coping mechanisms they used, and their self-esteem and the treatment condition of their disorder, i.e., the use of a brace or not. 82 children and adolescents ages 7 to 17 years who were attending an outpatient scoliosis clinic were administered two questionnaires; one evaluated emotional and behavioral factors linked to coping with stressful situations, and the second assessed self-esteem. Analysis showed that, after adjusting for emotion-focused coping, general self-esteem, and age, the effect of the use of brace as a treatment technique on the participants' emotional reactions was not significant.     

Pairwise likelihood estimation for confirmatory factor analysis models with categorical variables and data that are missing at random

Methods for the treatment of item non-response in attitudinal scales and in large-scale assessments under the pairwise likelihood (PL) estimation framework and under a missing at random (MAR) mechanism are proposed. Under a full information likelihood estimation framework and MAR, ignorability of the missing data mechanism does not lead to biased estimates. However, this is not the case for pseudo-likelihood approaches such as the PL. We develop and study the performance of three strategies for incorporating missing values into confirmatory factor analysis under the PL framework, the complete-pairs (CP), the available-cases (AC) and the doubly robust (DR) approaches. The CP and AC require only a model for the observed data and standard errors are easy to compute. Doubly-robust versions of the PL estimation require a predictive model for the missing responses given the observed ones and are computationally more demanding than the AC and CP. A simulation study is used to compare the proposed methods. The proposed methods are employed to analyze the UK data on numeracy and literacy collected as part of the OECD Survey of Adult Skills.     

The Transformative Effects of Stigma: Coping Strategies as Meaning‐Making Efforts for Immigrants Living in Greece

The present article examines the strategies that immigrants living in Greece use to cope with stigma that arises in their interaction with both Greek society and their communities of origin. Drawing on interviews and focus groups conducted with immigrants from a variety of countries, a dialogical analysis illuminates the ways in which immigrants actively negotiate stigmatizing perspectives and transform themselves. Strategies include the deployment of social categories such as those of ‘human being’ and ‘crazy’ person, and concepts such as those of ‘lawfulness’ and ‘fate’. These were used to construct meanings of equality and inclusion into society, to deny responsibility for stigma and to discredit stigma as absurd. They enabled participants to see themselves as proud, equal, self‐dependent individuals who plan actions for social change. The article suggests that coping with stigma should not only be understood in terms of stress regulation, leading to positive or negative outcomes, as suggested by current literature, but as a meaning‐making effort, through which individuals transform the way they see themselves and act within their world. A meaning‐making approach moves away from individualistic, outcome‐oriented explanations to a socially situated perspective on stigma that studies the processes through which social meanings are subjectively perceived as stigmatizing and are used to challenge stigma.
